Summary

Acoustic emission (AE) behavior from an woven SiC fiber-reinforced Si-N-C matrix composite during a quasi-static tensile test, both monotonic and repeated loading-partial unloading, was studied. AE signals were detected from the early stage of the loading and it continued up to fracture. The energy of acoustic emission below proportional stress was small, that above the proportional limit obviously became large. The Keiser effect-like behavior was recognized during repeated loading-partial unloading experiment. However, due to the formation of micro-fracture from an early stage of loading, the AE signals were generated during the unloading stage as well as the loading stage.
